VALVE-*OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 646,209, dated March27, 1900.

Original application filed January 15 1898, Serial No. 666.806. Dividedand this application filed January 23, 1900. Serial No. 2, 121. (Nomodel.)

To all whom it may concern.-

Be it known that I,J0HN WILLIAM GAYNER, a citizen of the United States,residing in the city and county of Salem, State of New J ersey, haveinvented a new and useful Improvement in Devices for OperatingValves,which improvement is fully set forth in the followingspecification and accompanying drawings.

This invention relates to means for operating a valve within a closedcompartmentfor instance, the feed-hopper of the fire-chamber of agas-producer; and it consists of a construction by means of which theescape of gas through the opening where the valveoperating lever passesthrough the wall of the compartment is prevented.

It further consists in the structural details hereinafter fullydescribed and claimed.

Figure 1 represents a central vertical section of a feed-hopper providedwith my improvement. Fig. 2 represents a side elevation of a portion ofthe same. Fig. 3 represents a horizontal section on the line w 50, Figs.1 and 2.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, in the particular embodiment of my inventionwhich I have selected for the purpose of illustrating the same, Adesignates a feed-hopper for the firechamber of a gas-producer ofwell-known construction, provided at its lower end with a valve-seat B,that is closed bya valve 0. Said valve 0 is controlled by a lever D,connected therewith and which extends through an opening E in the sidewall of the hopper. Surrounding the opening E and projecting from theWall of the hopper is a box F, that is provided with an opening G,situated opposite the opening E of the hopper. Said box F is preferablymade separate from the hopper and suitably secured thereto, as shown.The side walls of this opening G of the box F are straight and parallel,While the upper and lower walls are curved. The lever D is provided withan axial boss 11, having a central pivot-pin J, that is supported uponthe side of the box F. The boss H is cylindrical and fits closely withinthe opening G of the box, the upper and lower curved walls of theopening G being concentric with the pivot of the boss, so that a closejoint is maintained when thelever swings on its pivot.

It will be seen'from the foregoing description that the opening E of thehopper allows sufficient play of the inner limb of the lever D as thelatter is raised and lowered for operating the valve 0 and that the bossH of said lever closes the opening in the box con stantly when the leveris swung on its pivot and prevents the escape of gas through saidopening.

It will be seen from the foregoing that when it is desired to remove thelever D the valve G is disconnected therefrom and the boss H of thevalve detached. The lever D may then be Withdrawn and afterward restoredreadily, as will be apparent,which is, however, amat-- ter ofconsiderable difficulty as usually aooomplished through the top of thehopper,- owing to the length of said lever.

This application is a division of an appli-' cation filed January 15,1898, Serial No. 666,806.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A closed chamber having a valve-seat and provided with an opening inthe wall thereof, a projecting box surrounding said opening and providedwith an opening hav ing concentric end walls and situated opposite theopening in the chamber, a lever provided with an axial boss havingconcentric faces, said lever being pivoted upon the box with its bosssituated within and concentric with the walls of the opening therein,and a valve attached to the inner end of said lever.

2. "A closed chamber having a valve-seat, an opening in the wall of saidchamber, abox secured to said chamber and surrounding said opening, anopening in said box having concentric walls and situated opposite theopening in the chamber, a lever provided with an axial boss havingconcentric faces, said lever being pivoted upon the box with its bosssituated within and concentric with the walls of the opening therein,and a valve attached to the inner end of said lever.

3. A closed chamber having a yalve-seat, an opening in the wall of saidchamber, a box secured to said chamber and surrounding said opening, arectangular opening in said box the opening therein, and a valveattached t6 situated opposite the opening in the ehamthe inner end ofsaid level.

her the end Walls of said openin in the I 1 box havingconcentrically-curved faees, a JOHN WVILLIAM GAYNLR' 5 lever providedwith a cylindrical axial boss, Witnesses:
